Another object is to provide a paving block which may be readilyfastened to its Support or foundation and thereby held from warping andcreeping.

Another object is to provide a paving block which may be readily andeconomically manufactured.

According to this invention, the block is provided with a top havingvertical edges and a bottom having vertical edges and shaped to provideon each side a complerelates to a paving or covmentary flange and recesseach having a,

flat to The pavement or covering produced lb this block has each blockvertically and laterally interlocked in both directions with itsadjolning block on each side thereof. Y

Fig. 1 is a top plan view of a. single block;

Fig. 2 is a. bottom plan view thereof; Fig. 3 is a verticalcross-section of a pavement Iformed by the blocks, and

Fig. 4 is a plan view thereof.

The block has a top l which has a square or other suitable shape, and abottom 2 Y The pavement tb erewith. paving or covering which is integraltherewith and-hasn diferent shape.

he flanges project beyond lthe top'and the recesses extend underneath'the same.

block has each side Wit a flange and a recess to interlock it verticallyand laterally in both adjoining block on each side thereof.

'I he flanges. and recesses means, and further,` it may be cementedthereto. p

The block may be cemented to its adjoining block or blocks and therebya'L watertight joint formed between the same.

produced by the block set forth herein has. each block vertically andinterlockedV on each side thereof, and th tained in 'vertical and4lateral alignment When the block tends to move vertically relatively toits adjoining blocks, it does not cause its adjoining blocks to movelaterally away therefrom, as itv has vertical edges Hat top Hanges andrecesses.

Accordingly, a. pavement is *provided which will maintain stand .heavyloads and he invention set forth hereinl may d in various forms whichwill be with-l claims hereof.
